RE: Powder Coating
Powder coating was a piece of cake to learn, and I put together an entire rig for about $100.
$60 something from Harbor Freight for the powder coating machine, and around $30 for a toaster oven from WalMart. That way, it's dedicated to just this task, and no stinky / dangerous food or angry wife...
I soaked the aluminum parts in acetone to thoroughly clean them prior to coating. I found that it took more like 20-30 minutes, for the color to even out.
I was bugged by learning the process, but now in hind sight it's a piece of cake.
Here's an update on my build that had the powder coating stuff in it, along with pic's of the gear:
